28、nless otherwise specified, values set forth to establish the requirements for satisfactory performance apply to performance under both standard and extreme service conditions. When reduced performance under the extreme conditions is acceptable, tolerances or values setting forth acceptable variation

30、tation, that may exist aboard the air- craft, The stations that are to receive the release signals are those selected by the pilot on the aircrafts station select panel, not supplied as part of this equipment. 3.4.2 Modes of Release - The system herein described shall generate release signals, as de
31、scribed in 3.4.1, in the following manner: (1) To cause stores drop in ripple or step pairs (one from port and one from starboard). (2) To cause stores drop in ripple or step singles (one from port and then one from starboard), 4 Provided by IHSNot for ResaleNo reproduction or networking permitted w
32、ithout license from IHS-,-,-r MIL-A-1357 12 977990b 0359124 7 W MIL-A-81359(AS) (3) To cause stores drop in ripple or step salvo (one from each selected station simultaneously). When the system is in the ripple mode the described drops will continue at a selected drop interval described herein until
33、 the pilot has released the desired amount of stores (see 3.4.4). When the system is in the step mode the described drops will occur at a rate determined by the pilot, This rate will be one release pulse generated for each pilot depression of the weapon release button. 3.4.2.1 Ripple Pairs - When th
34、e ripple pairs mode is selected and one or more pairs of stations of equal inboard to outboard priority are selected the system will ripple stores simultaneously from each of the two highest priority stations selected (one port, one starboard) up to the quantity selected. If the amount selected is g
35、reater than the capacity of the pair, the station transfer signals will cause the system to ripple stores from the next highest priority pair selected, If there is no next highest priority pair selected, the system will not generate any further fire pulses. 3.4.2.2 Ripple Singles - The ripple single
36、s mode shall release one store from the highest priority station selected during one output pulse ; the next output pulse shall release one store from the opposite wing station of equal inboard to outboard priority if selected, If the opposite, equal priority station was not selected, the fire pulse
37、 shall be continuously directed to the highest priority station until it is completely depleted of stores if required by the quantity selection. If aEter depletion, more stores are required to be dropped, the station transfer signals shall cause drops to occur from the next highest priority station
38、selected. At this priority level, the drop shall again alternate between the same priority opposite wing stations if selected. If not, the drops shall continue to be directed to the single station as previously described in this paragraph. 3.4.2.3 Ripple Salvo - The ripple salvo mode shall cause the
39、 simultaneous re- lease of one store from each station seIected until the quantity of stores selected has been released. There is no regard to priority in the salvo mode. 3.4.2.4 Step Pairs - For the step pairs mode, there shall be a simultaneous release from both highest priority stations (similar
40、inboard to outboard priority) for each depression of the weapon release button. Priority and station transfer conditions shall remain the same as those described in 3.4.2.1. 3.4.2.5 Step Singles - For the step singles mode, there shall be a single release from the highest priority station selected f
41、or the first depression of the weapon release button. The next depression shall cause a release from the equal priority station on the opposite wing, if selected. These conditions of priority and station transfer are the same as those described in 3.4.2.2. 3.4.2.6 Step Salvo - The step salvo mode sh
42、all cause simultaneous release of one store from each station selected, provided it contains at least one store, for each depres- sion of the weapon release button, 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-A-81359 12 7997706 0359325 O =
43、3.4.3 Priority of Release - The system herein described shall generate release signals, as described in 3.4.1 in a priority manner as follows: (1) Outboard stations shall have-priority over inboard stations. As long as an outboard station is selected and contains stores, it shalllre- ceive the relea
44、se signals before any more inboard selected stations, regardless of its port of starboard location. (2) Opposite wing stations of equal outboard to inboard priority shall receive release signals alternately in step singles until one of the stations is depleted. At this time the release pulses will b
45、e directed to the other station and continue until that station is depleted. Then priority reverts inboard in the same manner. For maximum configuration the station priority shall. be as follows: Station (Port and Starboard) Priority 1 and 8 1 2and7 2 3 and 6 3 4 and 5 4 Center 5 3.4.4 Quantity Sele
46、ct - The number of release output pulses generated by the system ahall be pilot controlled, The pilot when desiring a drop of any amount of stores, shall be able to select the exact amount of from 2 to 40 output pulses to be generated in amounts limited to the following: (1) 1, 2, 3, 4, 5, 6 (steps
47、of one) (2) 8, 12, 16, 20 (steps of four) (3) 30, 40(steps of ten) When in the ainglee mode, one store will be depleted for each output pulse. In the pairs mode, two stores will be depleted for each output pulse. in the salvo mode, the number of btoree depleted for each output pulse will be equal to
48、 the number of loaded stores stations selected. 3.4.5 Rate of Release - The interval between successive release output pulses in the ripple mode ahall be pilot controlled and continuously variable between 20 and 2,000 milliseconds. The output pulse irterval shall be within 15 percent of the control
49、setting for etandard conditions and 110 percent for extreme conditions. In the step mode, each release pulse is initiated by a depression of the weapon release button. 6 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-3.4.6 enable the pilot to release stores when the programmer is in the off position, This will pro- vide a step release from selected stations, for each depression of the weapon release button.
